TEMPORARY BINDER.

SPECIFICATION forming part Of Letters Patent N0. 561 ,928, dated June 9,1896.

Application filed April 1, 1896. Serial No. 585,697. (No model.)

To all whom, it may concern.-

Be it known that I, JAMES R. VAIL, a citizen of the United States,residing at Ensley, in the county of Jefferson and State of Alabama,have invented certain new and useful Improvements in Temporary Binders;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

This invention is directed to improvements in devices for temporarilybinding together a number of sheets in book form, and has for its objectthe provision of a simply-constructed,

- efficient, and durable means by which the sheets may be assembledsingly or in bulk, and afterward removed with the minimum of time andlabor, and by which also the sheets when assembled are held againstaccidental detachment and are permitted a range of movement at theattached edge sufficient to afford easy access to the entire surface ofthe page for writing or other purposes.

The invention, by reason of the construction embodied, is applicable foruse in connection with any of the devices now employed to serve as abacking, cover, or closure for temporarily assembled sheets, and while Ihave shown my invention as applied to and formin g part of a book formof holder I do not wish it understood that I confine myself to suchapplication.

The nature of my invention will become clearly apparentfrom a reading ofthe following des'cription,when taken in connection with accompanyingdrawings, in which- Figure 1 is a perspective view of my improvedbinding device applied to a book form of holder, a number of sheetsbeing in place. Fig. 2 is an enlarged plan view, partly broken away, ofmy improved binding device. Fig.

3 is a sectional view on line a; a: of Fig. 2, and Fig. 4 is a sectionalview on line y y of Fig. 2.

Referring to the said drawings by letter, A denotes a metallic stripwhich forms the backing of my improved binding device, said strip beingprovided with side flanges a, and b is a second strip which is securedto the backingstrip by the flanges on the latter and by rivets c c, asshown.

At 2) b the strip 5 is perforated, said perforations being in pairs andlocated on opposite sides of the strip, each pair of perforations beingin transverse alinement and adapted to receive the ends cl d of one of anumber of staples (Z employed to hold the sheets in place. The stapleends in practice are passed through the perforations and rest againstthe strip A, and at d d are provided recesses which are engaged by aslidable locking-plate e, interposed between the strips and providedwith a fin ger-hold e, projecting through a slot b in the strip b. Thelocking-plate is recessed at c 2 said recesses serving, when moved intoalinement with the perforations Z), to free the staples, and when movedout of register the edges of the plate are caused to engage the recessesand lockthe staples in place.

I employ in connection with my improved binding device sheets previouslyperforated at the proper points, the perforated portion of the sheetbeing strengthened by a strip of cloth or other suitable material.

In the operation of my invention, supposing the staples to be locked inplace, the lockingplate is slid forward through engagement with theexposed finger-hold e, and all of the staples are thereby unlocked orreleased. Said staples are then removed and passed through theperforations in the sheets, after which the ends are caused to reenterthe perforations in the strip Z), and the plate being slid backward thelocking of the staples to place is effected.

The device, as will be clearly seen, is simple in construction, may becheaply produced, and is not liable to disorder, being constructed witha view to durability. The sheets may, by my invention, be quicklyinserted and removed, and when assembled are not liable of disconnectionwith ordinary use.

Various modifications both in the manner of construction and applicationof my improved device may be resorted to without departing from thespirit of my invention, as if desired I may construct the parts in a1nanner to permit adjustments to suit the size or number of sheets to beassembled, and in ranged between said strips and having a finger-holdproj eeting through the slot, and side reeessesadapted to be moved intoand out of register with the perforations, and a number of stapleshaving recessed ends adapted to be inserted in said perforations and tobe locked or released by the movement of the plate.

111 testimony whereof I affix my signature in presence of two witnesses.
